4. Compatibilizers in polymer blends having the structure of the polymers and oligomers I of claim 1.

5. Films, fibers and molded articles comprising the thermoplastic molding materials or thermosets of claim 2.

6. The polymer or oligomer of claim 1, wherein said polymer or oligomer has a number average molecular weight M.sub.n in the range from 300 to 15,000, and wherein the molecular weight distribution M.sub.w /M.sub.n is in the range of from 1 to 3.

7. The polymer or oligomer of claim 1, wherein said olefinically unsaturated C.sub.2 -C.sub.20 -hydrocarbon is selected from the group consisting of 1,3-butadiene, styrene,.alpha.-methyl styrene, ethene, propene, 1-butene, isobutene, 1-pentene, 1-hexene, 1-heptene, 1-octene, 1-nonene, and 1-desene.

8. The polymer or oligomer of claim 1, wherein said olefinically unsaturated C.sub.2 -C.sub.20 -hydrocarbon is selected from the group consisting of propene and isobutene.
